To (LIZ wit/mi it ntuq canoe/w:

Be it known that 1, PAUL KiinNE, a citizen of the United States, residing in New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented cer= tain new and useful Improvements in Corner-Beads, of which the following is a specification.

This invention relates to an improved corncr-bead f or protecting the edges of plastered walls at corners and other exposed portions ol the same; and the invention consists of a corner-bead which is made of sheet metal with a rolled-up bead at the edge and wings bent up in opposite direction to each other from said head, said wings being provided with bent-up edge flanges and with holes for the nails by which the wings are attached to the corner of the wall to be plastered.

The invention consists, further, of a device for connecting the ends of two adjacent corner-beads so that pieces of any length can be used, which connecting device will be fully described and claimed hereinafter.

In the accompanying drawii1gs, l*igure 1 represents a perspective view of my improved (1()I[l0I-l)(.l(l', showing it as attached to the corner of a wall before the plaster coating is applied thereto. Fig. 2 is a horizontal sec tion on line 2 2, Fig. 1. Fig. 3 is a side elevation of the corner-bead after the same is cut into shape and before the wings are bent up.

Fig. at is an end elevation. of Fig. 3. Figs. 5 and 6 are horizontal sections, respectively, on lines 5 5 and 6 6, Fig. 3. Fig. 7 is a detail perspective view of the connecting device between two adjacent sections of corner-beads, and Fig 8 is a portion of the improved corner-bead bent so as to be used for curved corner )ortions of the wall.

Similar letters of reference indicate corresponding parts in the several figures of the drawings.

Referring to the drawings, a represents the rolled-up edge bead, and b b the wings,of my improved corner-bead. The wings are bent up approximately at triangle of sixty degrees to each other at opposite sides of the head. The corner-beads are made from flat strips of sheet metal of any length, which are rolled up at one edge so as to l'orm the head a "and which are then cut in a suitable press by means of tapering knives transversely across the body of the strip, so as to form tapering wings I) I) and tapering. flanges b along the edges of the wings b b, as shown in Figs. 1

and 3. Simultaneously with the cutting of the wings nail-openings e are formed in the wings I) b by means of suitable punches or dies, which, like the knives, are arranged in the press, The wings I) b are then bent in opposite direction to each other approximately at an angle of about sixty degrees from the bead and placed in osition on the corner of the wall and attac ed thereto by driving nails through the nail-openings e into the wall alternately at one side of the corner and then at the other side of the corner of the wall, and so on, as shown in Fig. 1. The plaster covering is then applied over the wall, the corner-bead, and its wings, so as to be entirely embedded therein, as shown in Fig. 2.

As the sections of the corner-beads are made in any length desired, according to the various lengths of the sheet-metal blanks, it is neeessar to connect them at their adjacent ends y a suitable connecting device. This connecting device is formed of a short piece f of sheet metal, which is bent into a. 1

ollow bead f along one edge, which is clenched, so as to retain a coupling-wiref in position therein. Thesli htly-curved end of the iece f is then insertecFinto the open ends of t 1e beads a and curled up at the inside of the same, the bead f and the wire f being retained at the outside of the bead a, as

shown in Figs. 1 and 7, and locked in osition by means of a U-shaped wire staple which is passed through holes f* in the adjacent wings I) b and intertwisted with the ends of the wire f, as shown in- Fig. 1, so as to hold the adjacent ends of the heads a of two sections or lengths of corner-beads permanently together. Any other connecting device may be used, as I do not desire to confine myself to the special construction shown.'.

My improved corner-bead has the advantage of great cheapness, as the same can be made up from odd lengths or-'. a'ste strips of sheet metal which are obtained in the manufacture of sheet metal. It has also the advantage that the corner-beads are reliably held on the corner of the wall by the fasten ing-nails and by the plaster covering for which the wings, with their edge flanges, form anchors, the beads protecting the edge of the plastered corners of the wall. Another advantage is that corner-beads of any length can be made up by means of the connecting device, and, lastly, that the cornerbeads can be bent to any shape or curve without interfering with. their construction tion to each other from said bee or strength, as required'by the curved edgesof the walls to be plastere Having thus described any invention, 1 claim as new an desire to secure by Letters Petentl. A corner-bead consisting of an inte rel piece of sheet metal having a rolled-up e ge, and wings bent alternately in op osite direcsaid -wings being provided with tapering flanges at their sides and with holes for inserting the fasten- Ping-nails. v

2; A corner-bead consisting of an inte rel piece of sheet metal having a rolled-up e( ge, and wings bent alternately in op osite direction to each other from said bee said wings being slightly tapering-from their inner toward their outer ends and. rovided with tepering side flanges end nail-holes for the festeningqiails. t

The combination, with two adjacent lengths or sections of corner beeds provided with rolled-up edges, and wings bent alter-- nnteiy in opposite direction to each other scenes netely in opposite direction toeach other I vfrom said edges, of P. connecting device between the adjacent ends of the cornenheed sections, said connecting device consisting of e.- curled piece of sheet metal providedwith. e head at one edge, e connecting-wire in said head, and a wire staple essing through heies in the adj scent wings o the corner-heed sections, seid staple being intertwisted with the ends of the wire for locking the sections gether.

In testimony that i clstiin the foregoing as my invention I have signed my nziinein presence of two subscribing Witnesses. v
